DUMP-BODY MOTOR-TRUCK.

To all whom it may concern Be it known that 1, ROBERT citizen of the United States,

mode, in the county S. GAssAnY, a residing at Alaof Alameda and State of California, have invented new and useful Improvements in Dump- Body Motor Trucks, of which the following is a speificat1on This invention relates to motor trucks, and particularly to an improved dumping body for such trucks.

The object of the present. invention is to provide a substantial, capacious body for trucks in combination with means whereby the body may be shifted laterally to either side of the truck and adjusted in tipping posit-ion for the discharge of its contents.

.A. further object of the present invention is to provide means whereby the truck body may be manually operated; means being provided for locking the body in a centrally normal position upon the truck frame, and means being provided for automatically, actuating the sides of the body when the latter is adjusted into the position to one orvthe other sides of the truck. v

The invention consists of the parts and the construction and combination of parts as hereinafter more fully I claimed, having reference to the accompanying drawings, in which- Figure 1 is a side elevation partly broken away of amotor truck. Fig. 2 is an end view ofthe same with the dumping body in normal position. Fig. 3 is a plan view of the dumping body. Fig. 4 is an end view of the truck with the body adjusted in tilting position on one side. F1g.5 is a detail showing the shaft operating ratchet. Fig. (3 is a detail View of the stay rope. Fig. 7 is'a perspective view of the side door lever lock. Fig. 8 is a detail plan View of a body lock ing device. Fig. 9 is a perspective view of an adjustable connection for the tension ropes.

In the illustrated embodiment of my in vent-ion, 2 represents a portion of a suitable vehicle frame, having an appropriate running gear 3'to'which power may be transmitted through a transmission mechanism '4. Transversely mounted upon the upper part of the truck frame 2 is a pluralityof beams or members 5 upon which are described and Specification of Letters Iateut.

her is provided on each beam 5.

mounted bearings 6 of which a suitable num- Resting upon the upper surfaces of the rollers 7 of each beam 5 1s a series of tracksor tunnel irons 8, of suitable proportion, which are rigidly secured to the bottom 9 of a truck body formed by the sideslO and a front gate 11 and a rear' gate 12. The rear end of the body bottom 9 is shown as provided with a' substantial binding or angle iron, as 13, to which are fastened hinges 14 of i the rear or end gate 12. v

of the sides 10 are provided with hooks 15 which are adapted to enter the upper ends The upper rear ends of the angle or brace iron 13 by which the sides 10 are thus suspended. The lower.

edges of the sides 10 may be drawn snugly against the side edges of the bottom 9 by a suitable form of tongue 16 of which there is one on each side adapted to enter a corresponding tongue 17 securedto the adjacent portion of the bottom 9.

Both the forward end 11 and the rear end l2 of the body support at pivots 18appro- -priately shaped levers 19, the outer ends, of which are pivoted at 20 to the ends of the sides 10. The upper adjacent ends of the levers 19 may be locked together, when de sired, by a toggle connection comprisinga link 21 pivoted at 22 upon one of the upper ends of a lever 19. To the free end of the link 2.1 is pivoted a handle or lever 23, the handle having a slightly -l1ooked-sha ed prong 24. which is adapted to be insert in a perforation 25in the upper end of the adjacent lever, as clearly shown in Figs. 2 and 7.

The levers 19 on the rear end gate ,12 may be disconnected from the sides 10 by removing cotter pins 20 through the pivots 20 on the ends of the side" members 10. lVhen so released the levers 19 may swing downwardly with the. gate 12 as this is moved about its hinges l4.

Extending longitudinally with the frame 2 and below the body structure, there is pro.

which may be inserted vided a shaft 25, which may be mounted in or on the members 5, and secured to which.

shaft is a number of drums26 around each of which is wrapped a flexibleconnection .27, which is clearly shown in Fig. 2,then,passing oppositely from the drums 26 outwardly ---toward' guide sheaves 28 secured on the transverse members the ends of the connections 27 then being carried inwardly be neath the truck and cross as shown and finally connected to opposed fastening de-' 7 vices 29. Y

10 v 31 carrying pawls 32-33, one or the other ic a At the forward end ofthe shaft 25 is pro vided' a gear or ratchet wheel 30, Fig. 5.- Adjacent to the ratchet wheel 30 and loosely mounted on the shaft 25 is an oscillatory lever of wh may beheld in inoperative position :by a swivel rin or other suitable device 34 at the'upper en of the lever 31. By means ;of.the lever 31; and one or the other of pawls 32-413, the operator may ratchet the. gear 30, thus revolving the shaft which in turn winds the cables or connections 27 on the drums 26 so-that one end of the cableswill pull on the bottom9 ofthe truck body so that the latter may'be shifted toward that Side of. the tru'ck over which it is desired .to

' tilt'fthe car body; the tilted position'of the car body being indicated in Fig. 4;

As the operator through means of one of .the pawls 32 revolves the shaft25, and

through the cables or connections 27' pulls 1 the car. body to one side of the truck frame I as '2, the other ends of the cables 27 ,Will autoinatically play'ofi the drums 26. As the dumping approaches the side of the truck 2, the supporting rails or tracks 8 will runover the side rollers 7 and being unsupported atthe. outer portion the car body-will tilt to the position indicated in Fig. 4 resting on the inclined'ends of .the transverse members 5 of. the truck body.

. To insure a ainst too excessive a tiltingaction of the umping body, there is provided a plurality of flexible stays 35 which are shown in detail in' Fig. 6 as having at one end a rin .or collar 36 which may swing 'ortake-up device 37, such as shownin Fig. 9 5.

freely aroun of the stay being connected by an adjustable as compizlsing a clevis 38, havin a plura i of openin 39, throu h one 0 which may be inserte a pin or p 1t 40 over which is passed a ring or 41 to which is secured the end of the flexib e stay 35; the clevis 37 being secured to the bottom 9. When the, car body has been tilted to the desired position over one sided the truck 2, the flexible stay or stop device 35 comes into action to limit the further angular talting of:the car body by reason-of the connection of the latterthrough means of the-stay 35 to the relatively stationary bar 25 of the vehicle.

When the vehicle is travelingwith' the dumping .body 9 loaded and the sides 10 in appropriate adjusted pos1tion,"the upper ends of the levers 19 are normally locked to prevent the accidental loosening of the sides,-'but at the time it is desired to d imp the-shaft 25 the other en central the body the operator disconnects the toggle devices,2123, thus releasing the adjacent levers, and as the car body is shifted to one;

or the other side of the truck frame 2 through the winding of the cables or connections 27, then that one of the levers 19 7 on the end gate '12 which is be moved outwardl away from the truck body draw tig t a flexible connection or cable.

42, one end ofwhich is substantially con-- nected to the truck frame, as at 43, to the,

other end of which is connected an adjustable clevis 44 which is pivoted at 45inthe upper end. of a lever 19, therebein'g one of the flexible tension ro es or connections 42 for each lever 19 at't e forward and baclc ends of the truck body. v

When the car bod has reached alateral position over one si e of the'truckframe 2 and starts to tilt downwardly about the outermost bearing rollers 7,.the tilting action of the truck body draws tight the tension rope or connection 42 and this bein limited at one end 43 by the truck frame 'pu s on the outermost lever 19 rocking it about itsfulcrum 18, thus lifting' the side 10 to'whi-ch its lower end is connected and lifting the side to the position indicated in Fig. 4, thus permit-ting I the'disc'harge oft the contents of the'truck 7 body entirely to one sideof the frame 2.

By locating the pivots 20in the ends of dinal center line 0 the sides, this will cause the latter to tilt relative to-the levers 19 to the position shown in Fig.4, each-end of the sides being provided with small stops 46 which will rest on the ad'acent ends of the levers 19 when the side-1s lifted away from the-body of the trucki tf As the operator revolves the shaft 25 to wind the cables 27 over their respective drums and 'holds or shifts the car body back from an inclined to .a horizontal osition uponthe seve l rollers 7,, thecar ody .will be automatica lockedin its normally osition w n this is'approached by asui-tablelockin bolt 47, of which the is a suitable nu r provided; the bolt be' g slidable in;'a suit able bearing 48 attach to the lower surprojecte shown in the present instance at one of the bearings 6 of a\roll the sides 10 at a ointbelow the longitu- I I o devlce comprlsm 'a'fi ma.v

foration 50 therein when the bolt will automatically snap intov the perforation under. I' the force of a spring blfattached to the bottom 9. The bolts are manuallyreleasedfrom the keepers 49 by 'a suitable flexible connection 52-which passes forwardly and is connected to an operating lever 53 within reach of the operator of the vehicle. A pull on this lever withdraws the bolts 47 from the keepers 49 thus permitting the car body to be shifted laterally when desired.

Having thus described my invention, what I claim and desire to secure by Letters Pattent is 1. The combination with a traction frame having a plurality of transverse beams, of a laterally adjustable and tiltable box or body supported upon said transverse beams, adjustable. sides for said body, means for attaching the same to the bottom of the body, an adjustable end gate for the body, levers mounted upon said end gate and tie tachably connected to the ends of the sides, whereby the levers may swing down with said gate, and connections between said levers and said traction frame whereby whenthe box or body is laterally adjusted and tilted over the side of said frame the lower side of the body will be automatically raised.

2. The combination with a traction frame having a plurality of transverse beams, of a laterally adjustable and tiltable box or body supported upon said transverse beams, adjustable sides for said body, means for attaching the same 'to the bottom of the body, an adjustable end gate for the body, levers mounted upon said end gate and detaehably connected to the ends, of the sides, whereby the levers may swing down with said gate, connections between said levers and said traction frame whereby when the box or body is laterally adjusted and tilted over the side of said frame the lower side of the body will be automatically raised, and means whereby said levers may be locked to prevent the opening of the sides of the car body.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
